    • The method of detecting knocking of an internal combustion engine includes generating a sensor signal with a knock sensor provided with the internal combustion engine; digitizing the knock sensor signal to form a digitized signal; high-pass filtering the resulting digitized signal to form a high-frequency signal; counting amplitudes of oscillations the high-frequency signal which are greater than a first threshold value (P1) to form an amplitude count; integrating an absolute value of the high-frequency signal to obtain an integrated signal; comparing the integrated signal to a second threshold value (P2); and generating an output signal indicating that knocking is occurring when the amplitude count is at least one and when the integrated signal is greater than the second threshold value (P2).

    • An electromagnetic injection valve is proposed. The electromagnetic valve includes two magnetic coils that are wound in opposite directions and have the same characteristics on the same magnetic circuit, causing the forces of the magnetic coils to cancel each other out at the same excitation current. The two magnetic coils with canceling effect transforms the actual turn-on action of the valve, i.e., the opening of, the valve, into a turn-off action in one of the two coils. A rapid current drop is then determined by an extinction voltage. This makes it possible to achieve rapid force increase times without increasing the supply voltage. The valve can be controlled with a conventional switching output stage or with a current-regulated switching output stage. Reversing a differential current at turn-off also makes it possible to shorten the closing action.
    • 提出一种电磁喷射阀。 电磁阀包括在相同磁路上卷绕成相同方向并具有相同特性的两个磁性线圈,使得磁线圈的力在相同的激励电流下相互抵消。 具有消除效应的两个磁性线圈将阀的实际接通动作(即,阀的打开)转换成两个线圈之一中的关闭动作。 然后通过消光电压确定快速电流降。 这使得可以在不增加电源电压的情况下实现快速的力增加时间。 阀门可以用传统的开关输出级或电流调节开关输出级进行控制。 在关断时反转差动电流也可以缩短关闭动作。
